A prime number is prime because
It can only be multiplied by 1 and itself which makes it prime.
A number is composite because it can be multiplied by more than two factors.
factors: Two numbers you multiply together to come up with a number/answer.
Prime numbers are numbers that are only divisible by 2 numbers (one and themselves), for example 13, 17 etc.
To determine the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888, we can use the Prime Number Theorem. This theorem states that the density of prime numbers around a large number n is approximately 1/ln(n). Therefore, the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888 can be estimated by dividing ln(8888888888888888888888888888888888888888888888) by ln(2), which gives approximately 1.33 x 10^27 prime numbers.

Numbers that are not prime numbers are called composite numbers.
Prime numbers are divisible because any numbers that are divisible are prime. If a number isn't divisible, it isn't prime. Prime numbers have to be divisible by at least one pair of numbers to be prime.
